"Causes The lesions of hives and angioedema are caused by inflammation in the skin. In some cases, hives and angioedema are triggered when certain cells (mast cells) release histamine and other chemicals into your bloodstream and skin.
Allergic reactions to medications or foods can cause acute hives or angioedema. Many allergens have been identified. Examples include:
Foods. Many foods can cause problems in sensitive people, but shellfish, fish, nuts, eggs and milk are frequent offenders.
Medications. Almost any medication may cause hives or angioedema; common culprits include antibiotics, aspirin, ibuprofen (Advil, Motrin, others) and blood pressure medications.
Other allergens. Other substances that can cause hives and angioedema include direct contact with pollen, animal dander, latex and insect stings. "
